I tried both in SuperCollider and the Bottle does interesting thing. More
than I expected in just noise. The strip I have to try again with swapped
uv coordinates. It was just verry noisy.

Haha, go ahead. I'm not a musician. When I look at a piano it quickly
goes out of tune :)

Kind of the opposite of FFT is an intersting one. Massive additive
syntesis of sine waves. Check the ANS synthesizer. I have a basic
experiment working but have to extend that a lot more. Check
https://warmplace.ru/soft/ans/#about for what can be done. A goal for me
would be to create a collection of snippets of texture on a disc object
or polygon that can be placed in the scene and rendered to sound.

Then there's using splines as envelope's Attack Decay Sustain Release
(ADSR). You can use textures with tracks for rithmic patters. Extend that
idea to sequencers.
And before you know you are knee deep in DSP terretory with FIR filters
etc. https://www.musicdsp.org/en/latest/index.html

what would the Umbilic Torus sound like? :-)

a "modular synthesizer" include, combined with a "recording studio" include,
would make a nice base for exploration. anyway, please keep us in the loop on
developments.

Haha, yeah, well, have a look at VCV Rack https://vcvrack.com/ for that. I
actually wrote a few modules for it, but you'd have to compile them your
self. https://github.com/Moaneschien/4rack

Another great software for programmatic sound making
is Chuck : https://chuck.cs.princeton.edu/
And a few month ago, I'v tried to make some vidz from
sound files, with some gory software. Sorry, this is
in french, but I can translate a few explanation...

Oscillators:
https://ingoogni.nl/povray/sounds-of-povray/swing-povray-swing/
without sounds as they can be ear piercing and I have to figure out HTML
to set the player to a low volume.
But you can render the sounds yourself,

That's intersting!
Good idea to probe the surface in a circular motion so that there are no
discontinuities in the sound wave.

Properly closed splines also work well,

Audacity has function 'Sample data import' that I've used to make my own waves.
It is written in a float txt format that makes it eazy to import from POV.
I use POV splines to make a road height field and then used the same splines to
make the motor noise of a car.(it's on YouTube as MarsCarsII)
I like what you've done! Keep up the good work.
